Abstract

The present invention connects the piston and the push rod to absorb the angular change between the operation of the clutch pedal and the piston movement of the clutch master cylinder when the clutch pedal is operated, and the clutch pedal is stepped on the piston of the clutch master cylinder. In addition to pressurization, even when the push rod pulls the piston while the clutch pedal is returned, the clutch rod is stably maintained by maintaining a firm coupling state between the push rod and the piston to prevent the push rod and the piston from being separated. Provides operability.

Description

Clutch Master Cylinder

The present invention relates to a clutch master cylinder, and more particularly, a technique related to the structure of a portion receiving the operating force of the clutch pedal in the clutch master cylinder.

A clutch is mounted on a path for transmitting power generated from a power generator such as an engine of a vehicle to a transmission to switch a state in which power between the engine and the transmission can be controlled or connected.

Hydraulic clutch control system is configured to reduce the operating force of the clutch pedal by the operation mechanism of the clutch as described above, the hydraulic clutch control system is provided with a clutch master cylinder for generating the hydraulic pressure by the operating force of the clutch pedal, the clutch The release fork is provided with a release cylinder for operating the release fork by the hydraulic pressure supplied from the clutch master cylinder, the clutch master cylinder is a structure that is connected to the release cylinder through a hydraulic pipe.

In order to transmit the operation force of the clutch pedal to the clutch master cylinder, one end is connected to the clutch pedal and the other end needs a push rod connected to a moving piston while forming a straight stroke inside the clutch master cylinder.

1 illustrates a conventional connection structure between a piston and a push rod, and a spherical portion 504 is provided at an end portion of the push rod 500, and an insert piston 506 surrounding the spherical portion 504 is supported by a piston. It is configured to be integrated into the interior of the 508, the push rod 500 is capable of pivoting with respect to the piston 508, and occurs between the operating trajectory of the clutch pedal and the linear stroke of the piston 508 It is designed to absorb the angle change.

However, as described above, the spherical portion 504 provided at the end of the push rod 500 is wrapped and supported by the elastic force of the insert piston 506, so that the push rod 500 is the piston 508. ) May be pressurized, but when the push rod 500 exerts a force in the direction in which the piston 508 pulls the piston 508 while the clutch pedal is returned, the spherical portion 504 is pulled out of the insert piston 506. There is a case to come out.

The present invention has been made to solve the above problems, connecting the piston and the push rod to absorb the angular change between the operation of the clutch pedal and the piston movement of the clutch master cylinder during operation of the clutch pedal. In addition, when the clutch pedal is stepped on to press the piston of the clutch master cylinder, as well as when the push rod pulls the piston while the clutch pedal is returned, the push rod and the piston are firmly maintained to maintain the engagement state of the push rod and the piston. It is an object of the present invention to provide a clutch master cylinder that prevents the occurrence of separation.

Clutch master cylinder of the present invention devised to achieve the object as described above

A rod side yoke provided at an end of the push rod;

A piston side yoke provided on the piston side;

A spider each rotatably coupled to the rod side yoke and the piston side yoke in a state perpendicular to each other;

Characterized in that configured to include.

The piston side yoke is integrally formed with a separate insert piston inserted into and coupled to the piston;

The rod side yoke may be configured to be integrally formed with the push rod.

In addition, the clutch master cylinder according to the present invention

A piston installed to linearly move in the clutch master cylinder;

A push rod having one end connected to a clutch pedal to form a straight stroke toward the piston;

Universal joint connecting between the push rod and the piston;

Characterized in that configured to include.

The present invention connects the piston and the push rod to absorb the angular change between the operation of the clutch pedal and the piston movement of the clutch master cylinder when the clutch pedal is operated, and the clutch pedal is stepped on the piston of the clutch master cylinder. In addition to pressurization, even when the push rod pulls the piston while the clutch pedal is returned, the clutch rod is stably maintained by maintaining a firm coupling state between the push rod and the piston to prevent the push rod and the piston from being separated. Provides operability.

2 and 3, an embodiment of the present invention includes a rod side yoke 3 provided at an end of a push rod 1; A piston side yoke 7 provided on the piston 5 side; The rod side yoke (3) and the piston side yoke (7) is a structure configured to include a spider (9) which are respectively rotatably coupled in a state perpendicular to each other.

That is, the universal joint 11 connects the other end of the piston 5 installed to linearly move in the clutch master cylinder and the push rod 1 having one end connected to the clutch pedal to form a straight stroke toward the piston 5. It is a connected configuration.

In this embodiment, the piston side yoke 7 is integrally formed with a separate insert piston 6 inserted into and coupled to the piston 5, and the rod side yoke 3 is connected to the push rod 1. It was configured to be formed integrally.

Of course, the rod side yoke 3 may also be manufactured separately and may be integrally coupled to the end of the push rod 1 by a coupling method such as screwing.

In addition, the rod side yoke (3) and the piston side yoke (7) are both configured so that the engaging projection 13 is protruded to be coupled to the spider (9) itself rotatably, inserting a separate pin It is also possible to configure the rod side yoke 3 and the piston side yoke 7 with the spider 9.

When the piston 5 and the push rod 1 are connected with the universal joint 11 as described above, the push rod 1 can pivot with respect to the piston 5 during the operation of the clutch pedal. Thus, while the universal joint 11 smoothly absorbs the angular change resulting from the difference between the operation trajectory of the clutch pedal and the movement trajectory of the piston 5, the operating force of the clutch pedal can be smoothly transmitted to the piston 5. Can be.

In particular, in transmitting the operating force of the clutch pedal to the piston 5 through the push rod 1 as described above, when the push rod 1 transmits the operating force in the direction to press the piston (5) Of course, on the contrary, even when the push rod 1 is returned in the direction in which the piston 5 is pulled, the push rod 1 is connected to the piston 5 by a strong fastening state of the universal joint 11. No deviation from the valve is ensured, thereby ensuring the safety of operation of the clutch master cylinder.
